Default

Description

This option lets you specify the mode for offloading or tell the compiler to ignore language constructs for offloading.

Option -q[no-]offload is the replacement option for -[no-]offload, which is deprecated.

On Intel® Graphics Technology, the only options you can specify are /Qoffload- or /Qoffload:none, which tells the compiler to ignore language constructs for offloading. By default, offloading is optional for Intel® Graphics Technology.

If no -qoffload (Linux*) or /Qoffload (Windows*) option appears on the command line, then offload pragmas are processed and:

• The mandatory or optional clauses are obeyed if present

• If no mandatory or optional clause is present, the offload is mandatory

If any of the following appears on the command line, then offload pragmas are ignored:

• Linux* OS: -qoffload=none or -qno-offload

• Windows* OS: /offload:none or /Qoffload-

However, OpenMP* pragmas for coprocessor control (for example, omp target) are recognized if the [Q]openmp option is specified, regardless of whether or not offload pragmas are recognized or ignored.

If keywordmandatory or optional appears for [Q]offload, then offload pragmas are processed and:

• The mandatory or optional clauses are obeyed, regardless of the -qoffload (Linux*) or /Qoffload (Windows*) keyword

• If no mandatory or optional clause is present, then the -qoffload (Linux*) or /Qoffload (Windows*) keyword is obeyed

If the status clause is specified for an offload pragma, it affects run-time behavior.
